Statistical Shape Modeling To Quantify Variation In The Proximal Humeral Anatomy, Paul B. Sade Sr.

Electronic Theses and Dissertations

The fit of the humeral prosthesis to the intramedullary canal and the replication of the anatomic humeral head center are important factors in Total Shoulder Arthroplasty (TSA). The objective of this thesis was to develop a Statistical Shape Model (SSM) of the cortical and cancellous bone regions of the proximal humerus, and to assess potential shape differences with gender and ethnicity, with a goal of informing implant design. An SSM was used and Principal Component Analysis (PCA) was applied to data that represented both the cancellous and cortical humeral bone of 63 healthy subjects and cadavers. Anatomical measurements and PC …

Ior Methods In Unconventional Reservoirs Of North America: Comprehensive Review, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Unconventional resources have played a significant role in changing oil industry plans recently. Shale formations in North America have huge oil in place, 900 billion barrels of recoverable oil in Bakken only. However, the predicted primary recovery is still low as less than 10%. Therefore, seeking for improved oil techniques to increase oil recovery in these complex plays is inevitable. In this paper, three stages of review have been combined to find out the applicability of the most feasible IOR methods in these unconventional reservoirs. Firstly, the most common fluid and rock properties of these reservoirs have been investigated and …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Unconventional resources have played a significant role in changing oil industry plans recently. Shale formations in North America such as Bakken, Niobrara, and Eagle Ford have huge oil in place, 100-900 billion barrels of oil in Bakken only. However, the predicted primary recovery is still low as 5-10%. Therefore, seeking for techniques to enhance oil recovery in these complex plays is inevitable. In this paper, two different approaches have been integrated to investigate the feasibility of three different miscible gases which are CO₂, lean gases, and rich gases. Firstly, numerical simulation methods of compositional models have been incorporated …

Wellbore Stability Evaluation For Mishrif Formation, Ethar H.K. Alkamil, Husam R. Abbood, Ralph E. Flori, Andreas Eckert

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

During drilling operations for the E oilfield in the Mishrif formation in southern Iraq, stuck pipe has been identified as a significant geomechanical problem for several wells. In this study, a 1-D mechanical earth model (MEM) of the Mishrif formation is compiled based on its state of stress and rock strength parameters and is utilized to assess the contribution of borehole collapse leading to the stuck pipe problems. The MEM model is based on the principal in situ stresses and their orientation obtained from wireline logs measurements, measuring while drilling (MWD), and leak off test (LOT). Rock strength properties are …

Shale formations in North America such as Bakken, Niobrara, and Eagle Ford have huge oil in place, 100-900 billion barrels of recoverable oil in Bakken only. However, the predicted primary recovery is still low as less than 10%. Therefore, seeking for techniques to increase oil recovery in these complex plays is inevitable. In this paper, three different approaches have been combined to investigate the effect of molecular-diffusion mechanism on CO₂ huff-n-puff process in Bakken formation. Firstly, comprehensive review has been conducted on the reported experimental studies …

Optimizing Injector-Producer Spacing For Co2 Injection In Unconventional Reservoirs Of North America, Dheiaa Alfarge, Mingzhen Wei, Baojun Bai, Abdullah Almansour

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Shale oil reservoirs such as Bakken, Niobrara, and Eagle Ford have become the main target for oil and gas investors as conventional formations started to deplete and diminish in number. These reservoirs have a huge oil potential; however, the predicted primary oil recovery is still low as average of 7.5 %. Carbon dioxide (CO₂) flooding has been a controversial approach to increase oil recovery in these poor-quality formations. This study investigated the effect of injector-producer spacing, in range of 925-1664 ft, on CO₂ performance in these plays by using numerical simulation methods. CO₂ utilization value under …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

In order to address the conformance problem in high temperature and high salinity/hardness reservoir, an environmentally benign in-situ gel was developed based on hydrolyzed polyacrylamide (HPAM) and polyethyleneimine (PEI). Moreover, silica nanoparticle (SNP) was embedded to improve the performance of HPAM/PEI gel. To achieve the optimum formulation of HPAM/PEI-SNP gel, a comprehensive investigation was first conducted with the respect of gelation time, gel strength, and thermal stability. In addition, the particle size of SNP was determined by Dynamic Light Scatter (DLS) and the microstructure of HPAM/ PEI-SNP gel was characterized via Scanning Electron Microscopy (SEM). The optimum formulation, containing the …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Six males clad only in shorts were exposed to high levels of airborne di(n-butyl) phthalate (DnBP) and diethyl phthalate (DEP) in chamber experiments conducted in 2014. In two 6 h sessions, the subjects were exposed only dermally while breathing clean air from a hood, and both dermally and via inhalation when exposed without a hood. Full urine samples were taken before, during, and for 48 h after leaving the chamber and measured for key DnBP and DEP metabolites. The data clearly demonstrated high levels of DnBP and DEP metabolite excretions while in the chamber and during the first 24 h …

St. Louis Area Earthquake Hazards Mapping Project: Seismic And Liquefaction Hazard Maps, Chris H. Cramer, Robert A. Bauer, Jaewon Chung, J. David Rogers, Larry Pierce, Vicki Voigt, Brad Mitchell, David Gaunt, Robert A. Williams, David J. Hoffman, Gregory L. Hempen, Phyllis J. Steckel, Oliver Salz Boyd, Connor M. Watkins, Kathleen B.

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

We present probabilistic and deterministic seismic and liquefaction hazard maps for the densely populated St. Louis metropolitan area that account for the expected effects of surficial geology on earthquake ground shaking. Hazard calculations were based on a map grid of 0.005°, or about every 500 m, and are thus higher in resolution than any earlier studies. To estimate ground motions at the surface of the model (e.g., site amplification), we used a new detailed near-surface shear-wave velocity model in a 1D equivalent- linear response analysis. When compared with the 2014 U.S. Geological Survey (USGS) National Seismic Hazard Model, which uses …

Differential Gene Expression Analysis Of Metolachlor Treated Human Liver Cells By Microarray, Navinder Paul Kaur Brar

Dissertations and Theses @ UNI

Metolachlor is one of the most common pre-emergent pesticides used by Iowa farmers. It is used to control broadleaf weeds and grasses in the fields of corn and soybean. It is a frequent contaminant of groundwater and surface water due to runoff after application. It has been shown to inhibit protein and chlorophyll synthesis in plant cells, but its effect on mammalian cells has not been consistently conclusive. As metolachlor and other herbicides have been shown to be associated with harmful health effects in non-target organisms it is very important to determine a mechanism of action on non-target cells, especially …

Smartphone Based Ubiquitous Sensing Platform Leveraging Audio Jack For Power And Communication, Ranjana Joshi

Dissertations and Theses @ UNI

With the popularization of smartphones, various smartphone centric ubiquitous sensing applications, which use a smartphone in conjunction with external sensors for data acquisition, processing, display, communication, and storage, have emerged. Because smartphones do not have a universal data interfaces, many ubiquitous sensing applications use the earphone and the microphone channels of the 3.5mm audio interface for data communications so that they can work with various types of smartphones. The earphone channels of the 3.5mm audio interface can only send AC signal out of a smartphone, hence DC power needs to be harvested from the earphone channels.

In this research, based …

Anthropocentrism, The Other Face Of Patriarchy: An Investigation Into Patriarchal Attitudes And Perceptions Of Non-Human Nature, Alexis St. Claire

Dissertations and Theses @ UNI

Attitudes about gender and ethnicity are a critical dimension for understanding how human behaviors impact the climate. Plumwood (1997) argued that conceptually humans relate to the environment is ideologically connected to the way dominant and oppressed groups interact. Past research has found that exposure to nature decreased negative body image and other mental health issues that are connected to oppressive ideologies (Gidlow et al., 2016; Goldenberg & Soule, 2015; Holloway et al., 2014). The current study explicitly tested the link between patriarchal attitudes and connectedness to nature among a student group. It was found that higher levels of patriarchal attitudes …

A Study Of Scattering From Snow Embedded With Non-Spherical Shapes Of Scatterers With Relaxed Hierarchical Equivalent Source Algorithm (Rhesa), Chan Fai Lum, Fu Xin, Hong Tat Ewe, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Remote sensing has been used widely in studying the earth terrain such as snow or sea ice due to its fast, convenient and long-term monitoring capabilities. SAR images acquired could be used to analyze the condition of snow, snow water equivalent (SWE), surface roughness and others. Theoretical models have also been developed to understand how microwave interacts with the snow medium and the scatterers embedded inside the medium. Conventionally, spherical shape of scatterers is commonly used to represent the ice particles embedded inside snow where the actual shape of scatterers can vary. This paper is to present a theoretical model …

The Rise Of The Far Right: Explaining Popularity And Potential Influence, Vanessa Rosato

Scripps Senior Theses

The 2016 election cycle has shown a dramatic radicalization of the right, featuring elements such as out-group demonization, law and order rhetoric, and populist strategies that have not been so prevalent in the US since the rise of Nixon’s Silent Majority in the 1970s. The UK has experienced a similar ideological shift, though its emergence has perhaps not been so notoriously outspoken. All the same, the fervent anti-statist and anti-elitist narrative employed by the Leave Campaign is starkly similar to language historically associated with the populist rhetoric of the Far Right. Drawing on analyses of economic, socio-cultural, and geopolitical trends …

Isolation And Spectroscopic Characterization Of Zn(Ii), Cu(Ii), And Pd(Ii) Complexes Of 1,3,4-Thiadiazole-Derived Ligand, Dariusz Karcz, Arkadiusz Matwijczuk, Bozena Boron, Bernadette Creaven, Leszek Fiedor, Andrzej Niewiadomy, Mariusz Gagos

Articles

A series of complexes incorporating Zn(II), Cu(II), and Pd(II) ions, and 4-(5-heptyl-1,3,4-thiadiazol-2-yl)benzene-1,3-diol (L1) as model ligand, was synthesized in order to examine the nature of potential interactions between biologically active ligands, 1,3,4-thiadiazoles and metal ions with proven biological relevance. The structures of the compounds isolated were characterized using a number of spectroscopic methods including IR, Uv–vis, AAS, steady state and time-resolved fluorescence (TRF). The results obtained suggest that the L1-Zn(II) and L1-Pd(II) complexes consist of one molecule of L1 and one acetate ion acting as ligands, while the L1-Cu(II) complex adapts a 2:1 (L1: metal) stoichiometry. The coordination of L1 …

Mechanisms Of Vasovagal Syncope In The Young: Reduced Systemic Vascular Resistance Versus Reduced Cardiac Output, Julian Stewart, Marvin Medow, R Sutton, Paul Visintainer, D Jardine, W Wieling

NYMC Faculty Publications

BACKGROUND: Syncope is a sudden transient loss of consciousness and postural tone caused by cerebral hypoperfusion. The most common form is vasovagal syncope (VVS). Presyncopal progressive early hypotension in older VVS patients is caused by reduced cardiac output (CO); younger patients have reduced systemic vascular resistance (SVR). Using a priori criteria for reduced CO ( downward arrowCO) and SVR ( downward arrowSVR), we studied 48 recurrent young fainters comparing subgroups of VVS with VVS- downward arrowCO, VVS- downward arrowSVR, and both VVS- downward arrowCO& downward arrowSVR. METHODS AND RESULTS: Subjects were studied supine and during 70-degrere upright tilt with a …

Sola Scriptura Statuat Lex Orandi: Toward A Transcultural Theology Of Liturgy, David A. Williams

Faculty Publications

The Seventh-day Adventist church is one of the most diverse religious groups. With this diversity comes a preponderance in worship practices. Calling upon the Reformation principle, sola scriptura, the Bible alone should establish the rule for liturgy. How do we apply the Bible as the rule for liturgy, with so many worship preferences and diversity of cultures within the Adventist church? In this paper, I seek to articulate a way forward, developing a transcultural theology of liturgy to be applied in every Adventist culture, allowing room for a rich variety of local cultural contextualizations.

The Worship Experience We Long For: The How Of Worship, S. Joseph Kidder

Faculty Publications

Have you ever longed for meaningful worship? In the previous article of this series, we discovered that God’s identity as the powerful and good God is the reason—the why—of worship. Now that we know the why behind our worship, it’s time to answer the question of how. Amidst all our discussions of worship, we often center on the style of worship. The intent of this article is to describe how to behave in a worshipful way, whether in a personal or corporate setting, given insights gleaned from Psalm 100.

A Research Agenda For The History Of Property Law In Europe, Inspired By And Dedicated To Marc Poirier, Anna Di Robilant

Faculty Scholarship

Proposes the following research agenda: (a) understanding the relation between property and long-term economic change by focusing on the relation between property law and what historians call "social property" relations; (b) understanding property concepts and ideas in the context of the larger ideological and philosophical ideas that shaped the immediate world of jurists and property lawyers; (c) looking beyond the single, contingent episodes of the history of property law and identifying longterm patterns and regularities in the way jurists conceptualized property; and (d) understanding European property culture in its many entanglements with the non-European world.

Trusting Big Data Research, Neil M. Richards, Woodrow Hartzog

Faculty Scholarship

Although it might puzzle or even infuriate data scientists, suspicion about big data is understandable. The concept doesn’t seem promising to most people. It seems scary. This is partly because big data research is shrouded in mystery. People are unsure about organizations’ motives and methods. What do companies think they know about us? Are they keeping their insights safe from hackers? Are they selling their insights to unscrupulous parties? Most importantly, do organizations use our personal information against us? Big data research will only overcome its suspicious reputation when people can trust it.

Some scholars and commentators have proposed review …

On Questioning Automation, Woodrow Hartzog

Faculty Scholarship

Given the rapid pace of innovation and adoption, it can be hard to make sense of automated technologies. New products that leverage algorithms and artificial intelligence seem to be both promising and frightening. Law and policymakers, as well as the general public, are grappling with when to be excited and when to be concerned. If you're confused, you're not alone

The Selection Of Litigation Against Government Agencies: Evidence From China, Wei Cui, Zhiyuan Wang

All Faculty Publications

We test the relevance of the selection theory of litigation in a contemporary, civil law setting, using Chinese judicial data that span 25 years regarding lawsuits against government agencies. Civil law systems may be characterized by lower costs of litigation and lower rates of settlement than the U.S. legal system, and therefore the presence of selection effects cannot be assumed. We show that selection effects are indeed manifest in Chinese administrative litigation, and suggest that this may be explained by hidden or intangible litigation costs. Our test for selection effects builds on the approach of previous U.S. studies and potentially …

Flexible Regulation Scholarship Blossoms And Diversifies: 1980-2012, Cristie Ford

All Faculty Publications

This piece reviews the 198 US law review articles that were most influential within flexible regulation scholarship (which includes meta regulation, responsive regulation, reflexive law, principles based regulation, new governance, and more) between 1980 and 2012, which also discussed innovation. It is chapter 4 of a forthcoming book on financial innovation and regulation. The analysis demonstrates that across this time period, flexible regulation scholars advocated for regulatory structures that were permeable to three main non-legal forces: market forces, deliberation and community norms, and industry standards. The image that emerges is of a diverse scholarly community, within which many adopted economics-derived …

Equality And The Defence Of Provocation: Irreconcilable Differences, Isabel Grant, Debra Parkes

All Faculty Publications

Recent amendments to the defence of provocation have limited access to the defence to those who are provoked by conduct that, if prosecuted, would have been an indictable offence punishable by at least five years imprisonment. The paper argues that these amendments are both over- and under-inclusive and fail to confront the central problem surrounding provocation which is that it privileges loss-of-control rage often in the context of male violence against women or in response to same-sex advances. The paper supports the abolition of the defence of provocation but only if mandatory minimum sentences for murder are abolished providing trial …

Sex With Sweethearts: Exploring Factors Associated With Inconsistent Condom Use Among Unmarried Female Entertainment Workers In Cambodia, Siyan Yi, Sovannary Tuot, Pheak Chhoun, Khuondyla Pal, Chanrith Ngin, Kolab Chhim, Carinne M. Brody

Background: Despite the success in promoting condom use in commercial relationships, condom use with regular, noncommercial partners remains low among key populations in Cambodia. This study explores factors associated inconsistent condom use with sweethearts among unmarried sexually active female entertainment workers (FEWs).

Methods: In 2014, the probability proportional to size sampling method was used to randomly select 204 FEWs from entertainment venues in Phnom Penh and Siem Reap for face-to-face interviews. Multivariate logistic regression analysis was conducted to examine independent determinants of inconsistent condom use.

Results: Of total, 31.4% of the respondents reported consistent condom use with …

To Err Is Human: Can American Medicine Learn From Past Mistakes?, Jeffrey B. Ritterman

The history of medicine includes many errors. Some persisted for decades and caused great harm. Several are highlighted in this article, including the mythical thymic diseases: thymic asthma and status thymicolymphaticus. Some medical mistakes, such as the diet-heart hypothesis of Ancel Keys, continue to cause harm. To avoid future errors and their associated harm, I suggest a cultural shift encouraging professional humility and greater questioning of medical dogma. Medical education focused on teaching students this history may help with this cultural shift.
